I am having a problem installing this update. When I startup my laptop, Avast tells me wy software security is critical and its this update it prompts me with. I have downloaded the install and run it several times but it wont install. It appears in my task manager running at 23140K and between 00 and 02 CPU but thats all it does. Then eventually its time for me to go to bed and shut down my laptop until the next time when I have to go through it all again.
